Application filed December 6, 1913. Serial No. 805,030.

To allwhom it may concern:

Be it known that I, CALEB Gr. COLLINS, a

citizen of the United States of America, residing at Woodmere, Nassaucounty, New Y York, have invented new and useful Improvements in Devicesfor Removing Particles. from Gases or Fumes, of which the following is aspecification.

This invention relates to a device for removing from gases or fumesparticles which may be carried thereby or held in suspension therein.

One of the objects of the invention is to provide a device of thischaracter in which the particles which are to be extracted-from thegases or fumes containing the same are extracted in a dry state.

Other objects of the invention are to provide a device of this characterwhich is simple in construction, which is not costly to manufacture andwhich is simple and reliable in operation.

Other objects will in part be obvious and in part be pointed outhereinafter.

For purposes of illustration the invention is described in connectionwith the removal of nascent sulfur from fumes or gases containing thesame, but it is of course. understood that the invention is applicableto. I other ticles.

I gases or fumes carrying solidpar arrows. The baflle plates 4, it willbe seen,'

divide the casing into a plurality of compartments in each of whichthere is placed a material 5 of such a character that the gases or fumesmay pass therethrough, but

any particles carried by, or held in suspen-' sion by the thereon. j

c it has been found that .excelsior or asbestos fiber will answer thepurpose and give beneficial results, it is of course understood that anyother similar substance which gases or fumes, will be deposited terial 5is placed. To the bottom of each receptacle is attached a rod 7 whichpasses through the bottom of the casing 1 and to the lower end of whicha friction roller 8 is secured. -Extending beneath the casing 1 1s ashaft 9 provided with cams 10 adapted to engage the friction rollers 8.This shaft 7 may be rotated in any suitable manner, as for example bymeans of a belt (not shown) engaging the pulley 11. Each of the cams isso shaped that as the shaft rotates the cam will cause the receptacle 6to alternately rise and fall, the downward motion of the receptaclebeing preferably due to gravity. The cams are furthermore so shaped thatthe downward motion of the receptacle will be abrupt or sudden, wherebythe bottom of the receptacle comes in contact with stops 12 or the like,whereby the material within the receptacle will be subjected to a joltwhich will cause the deposited substance contained within the materialto be shaken out therefrom and to drop by gravity to the bottom of thecasing 1.

As indicated in the drawing the cams are preferably so positioned as toact successively on alternate receptacles 6, whereby as one receptaclerises the adjacent receptacles will be falling. In order to guide themovement of the receptacles. guides 13 are provided which are secured tothe baflle plates 4. The top of the casing 1 is provided with openingsregistering with the receptacles, which openings are normally closed bysuitable cover plates 14:. g

. The operation of the device which should be obvious from the abovedescription is as follows: The fumes or gases containing the sulfur orother particles which it is desired to remove therefrom enter; thecasing by means of pipe 2 and pass therethrough as ini moved whendesired in anysuitable manner.

While 6 receptacles are shown it is of course understood that theinvention is not limited to this number, it being only necessary to havesufiicient material 5 to remove the particles carried by the gases orfumes.

Having described the invention, in connection with an embodiment thereofto the details of which the invention is not of course to be limited,what is claimed as new and what is desired to be protected by LettersPatent is set forth in the appended claims e 1. In a device of the classdescribed, in combination, a casing provided with an inlet and with anoutlet, a plurality of bafile plates provided within the casing instaggered relation to each other to provide intercommunicatingcompartments, receptacles mounted for reciprocation Within the saidcompartment, filter material mounted within each receptacle, and meansfor agitating the receptacles alternately.

2. In a device of the class described, in combination, a casing providedwith an inlet and with an outlet, baflle plates provided with the casingin staggered relation to each other and affording intercommunicatingcompartments, receptacles mounted for reciprocation w1th1n the saidcompartments,

I filter material mounted within each recepably within said casing,means within said casing for collecting particles carried by gases orfumes passing through the casing, a projection extending from the lowerpart of said receptacle to the bottom of the casing, a shaft ournaledbeneath the casing, a cam carried by the said shaft and adapted tooperativelyengage said projection to operate the receptacle, and abumper provided within the casing beneath the receptacle for engagementwith the same during its downward movement.

4. In a device of the class described, in combination, a casing providedwith an inlet and an outlet, a receptacle within said casing, meanswithin said receptacle for collecting particles carried by gases orfumes passing through the casing, a projection extending from the lowerpart of said receptacle and through the bottom of said casing, a shaftbelow said casing and a cam carried by said shaft and adapted tooperatively engage said projection to reciprocate said receptacle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CALEB G. COLLINS.
